The major system outputs of the National Forest Carbon Monitoring, Accounting and Reporting System (NFCMARS) include the National Inventory Report and policy development support.

National Inventory Report

To fulfill its reporting obligations under the United Nations Framework Convention on Climate Change (UNFCCC), Canada must prepare an annual National Inventory Report detailing the country’s greenhouse gas emissions and removals.  The report covers emissions and removals in all sectors of Canada’s economy, including Agriculture, Forestry and Other Land Uses.

Overall responsibility for the development and publication of the National Inventory Report resides with the Greenhouse Gas Division at Environment Canada. The Canadian Forest Service uses NFCMARS to contribute estimates of emissions and removals in Canada’s forests, including emissions and removals associated with land conversion to and from forests.

Diagram of the institutional arrangements for production of the National Inventory Report. The Canadian Forest Service at Natural Resources Canada, through NFCMARS, and Agriculture and Agri-Food Canada, through CanAgMARS, work together and exchange data for land-use change and afforestation, reforestation and deforestion. Data from different divisions, in addition to other data for energy, solvents, industrial processes and waste, are sent to the Greenhouse Gas Division at Environment Canada to be included in the National Greenhouse Gas Inventory.


LULUCF = Land-Use, Land Use Change and Forestry
GHG = Greenhouse gas
C = Carbon
NRCan = Natural Resources Canada
CFS = Canadian Forest Service
LUC = Land use change
ARD = Afforestation, reforestation, deforestation
AAFC = Agriculture and Agri-Food Canada

Policy development support

The carbon accounting team of the Canadian Forest Service works in close collaboration with both federal and provincial government policy makers to help ensure that forest policy development is supported by sound science.

Climate change and the introduction of greenhouse gas emission reduction targets have brought new challenges to the forest sector. The forest sector is different from most other sectors in that it can provide carbon “sinks” to offset greenhouse gas emissions from other sectors. Forest carbon sinks are difficult to measure, and developing policies that encourage good carbon management while reinforcing the sustainability and competitiveness of the forest sector is no small challenge.

A good understanding of forest carbon dynamics and the factors that control the forest carbon budget is required. The carbon accounting team works with policy makers to provide relevant and timely scientific information and to ensure that complex scientific issues are synthesized in a manner that allows these issues to be taken into consideration during the policy development process.
